The most sound per pound: That's the Wharfedale D320 bookshelf loudspeaker in a nutshell. Compact enough to fit practically anywhere you want, with a soft, refined, contemporary look distinguished by radiused corners and a curved front baffle, D320 belies its size (and cost) to play with riveting levels of clarity, punch, airiness, and detail. And yes, D320 knows the definition of deep, controlled, and efficient bass. It can even be placed close to rear walls, expanding your setup options & showing off its flexibility in any number of configurations.
Featuring drivers based off those used in the company's Diamond 11 Series, D320 is created to redefine the notion of "budget" by way of a smart industrial design from award-winning Keiron Dunk & acoustics helmed by famed British engineer Peter Comeau. And when you consider D320 boasts 5" woven Kevlar cone bass/mid driver, a super-long-throw voice-coil motor system complete with a custom-shaped one-piece pole plate fitted with a copper cap, & oversized ceramic magnets, and you begin to wonder how the model can sell for under $350 / pair. We should also mention the presence of Wharfedale's trademarked WFR ( Wide Frequency Response ) 1" tweeter that incorporates its own cabinet – and a trademarked P-EQ ( Pressure Equalization ) port system. Both stem from developments in the costlier Diamond 11 Series.
Spectacular technology & build aside, your job is to solely enjoy the arresting performance delivered by D320 on basically every type of music that comes to mind. And we know you won't have any problem falling in love with D320. High-frequency responsiveness, emotional expressiveness, midrange definition, & substantial sound-stages are no longer the exclusive parlance of much more expensive speakers. Ditto advanced cabinet construction, which on D320 takes the form of profiled 1.1-inch-thick front baffles that reduce diffraction reflections. Critically braced panels, fiber-lined walls, and a software-developed crossover with low-loss polypropylene capacitors and laminated core inductors further D320's smooth, seamless, & resonance-defeating qualities – allowing you to enjoy more music as the artists intended it to be heard.
"Where it does come into its own is with a remarkably accurate and neutral sound that handles all kinds of music styles without fear or favor. Furthermore, there is a sense of fun and energy to it when you play something with a little spark."

Advanced Bass & Midrange Drivers
For the bass/mid drivers, the latest generation of Wharfedale's long-established woven Kevlar cones are bonded to a super-lightweight surround made of hi-tech foamed polyether, delivering remarkable clarity, texture. & musical expression. These cones are driven by a super-long-throw voice coil motor system, enabling low-frequency linearity & accuracy that is exceptional for such low-cost loudspeakers. The use of a specially shaped one-piece pole plate fitted with a copper cap reduces inductance and controls the magnetic flux, ensuring low distortion.
Trademarked WFR Treble Unit
Developed for the Diamond 11 Series and fine-tuned for the D300 range, Wharfedale's WFR ( Wide Frequency Response ) tweeter incorporates its own cabinet, a precisely shaped rear chamber damped with a fiber filling. An over-sized ceramic magnet, selected to give a smoother transition from midrange to high frequencies, is attached to a pole piece with copper cap for flux control. The pole piece is vented through to the rear chamber to achieve a low resonant frequency, ensuring excellent linearity & allowing the textile dome, sited within a dished waveguide, to contribute to a wonderfully lucid midrange as well as smooth, pure, & richly defined high-frequency detail.
P-EQ Bass Reflex Port
Developed from the Slot-Loaded Distributed Port found in Diamond 11 Series, the D300 Series' P-EQ ( Pressure Equalization ) port system is critical to the speakers' deep & controlled bass performance. Low-bass frequencies emitted from the rear surface of the bass driver travel through a downward-firing port in the base of the speaker, with precisely curved openings to smooth airflow. These frequencies exit into the room omnidirectional through a gap between the cabinet and the surface on which it rests ( or, in the case of the D330, between cabinet & plinth ), formed by four feet attached to the speaker's base. This reduces the pressure differential between the high pressure in the port and the low pressure in the room, thus eradicating the turbulence & audible 'chuffing' suffered by conventional ported systems whilst aiding bass reflex efficiency.
Custom Crossover & Cabinet Design
The output of the drive units is carefully combined by a thoroughly researched crossover developed using Wharfedale's Advanced Software and Listening Iteration system. Each crossover is carefully evaluated using a wide range of music, with the emphasis being on the lifelike reproduction of voices & instruments in addition to the dynamics of the musical performance. Crossover components feature low-loss polypropylene capacitors & laminated core inductors for optimum transfer of the music signal.The acoustically profiled cabinets feature 28 mm-thick front baffles, a luxury, engineering touch to such low-cost speakers – profiled at the edges to reduce diffraction edge reflections at mid-to-high frequencies. Critical bracing of the cabinet panels contributes to the eradication of audible resonance and, combined with the rounded cabinet edges, yields a rigid base on which to mount the drive units. In addition, the cabinet walls are lined with a specially developed internal fiber, chosen for its outstanding absorbent qualities across a wide bandwidth. You'll hear the drive unit output unsullied by unwanted colorations caused by panel vibration or internal resonances, revealing more of the detail of the musical performance.
